Jumper!

Jumper! is a freeware platform game starring Ogmo, a creature created in a lab by the army as a weapon of mass destruction. After all attempts to contain it fail, Ogmo escapes from the cell and starts to negotiate the many traps left on every room of the abandoned research base to finally break free. The main character is controlled with the arrow buttons: left and right for movement, up for jumps. Ogmo is able to do a double jump in mid-air, somersaulting to land on high places.

Each screen is configured as a self-contained puzzle with many devices and platforms. Progress is automatically saved at the start of each room. Ogmo has to be guided to the exit, carefully avoiding contact with hazardous features like spikes, lightning arcs and bottomless pits. Helpful items like golden arrows and super pads have to be touched to give extra jumps, allowing Ogmo to deftly reach a top platform. There's a level editor included to create custom puzzles.
